  • Does this answer your question? [Check if an array of strings contains a substring in javascript](https://stackoverflow.com/questions/44440317/check-if-an-array-of-strings-contains-a-substring-in-javascript) – Heretic Monkey Apr 03 '20 at 13:00
  • The reason it was closed is because you should not expect SO users to provide a complete solution without showing what you have tried, your research, where you hare stuck. SO is not a coding service. But you got lucky, someone answered. – Nic3500 Apr 04 '20 at 23:58

You can use Array.map() and String.includes() to achieve this, as followings:

let arr = ["Drinks:Focus", "Baked:No", "Addons:320"]

arr = arr.map(item => item.includes('Drinks') ? item.replace('Drinks','Beverage') : item)

console.log(arr)
